Teaching you French, I got into trouble (7)
I believe the answer is:
tuition
'teaching' is the definition.
(I know that tuition is a type of teaching)
'you french i got into trouble' is the wordplay.
'you french' becomes 'tu' ('you' in French).
'got' says to put letters next to each other.
'trouble' is an anagram indicator.
'into' is an anagram of 'tion'.
'tu'+'i'+'tion'='TUITION'
(Other definitions for tuition that I've seen before include "Lessons" , "Training" , "practice" , "Personal coaching" , "Schooling" .)
